Title: Plate catalyst used in hot waste gas - has coated metal support roughened by blasting with hard material, giving good adhesion at low cost
Inventor: HUMS ERICH DIPL-CHEM DR
IPC: B01J37/02
Filed: 1991-09-30
Abstract: Plate catalyst (I) for use in hot waste gases has a surface roughened metal support (II0 and catalytically active coating (III). Before coating, (II) is roughened by mechanical erosion with a gas jet (IV) mixed with hard, broken, special blasting agent (V) to a median roughness Ra = 2-7 microns and mean depth of roughness Rz = 16-40 microns (DIN 4768). (V) has a grain size of 4-10 microns and pref. is a silicide, nitride, aluminide, metallised glass or corundum. (IV) has a relative velocity of 0.7-1.5 m/min and pressure of 3-6 bar. The nozzle is 40-100 mm from (II). USE/ADVANTAGE - (I) is used in the denitrification of hot flue gas from fossil fuel power stations. Roughening (II) improves the adhesion of (III) and reduces the cost of mfr., since very costly and time-consuming flame spraying of Al is unnecessary. In an example, stainless steel sheet was made into expanded metal, then degreased and placed 40 mm below a series of 12 nozzles. The nozzles were supplied with oil-free compressed air at 4 bar, to which silicide and aluminide with a granulation of 7-8 microns were added. The velocity was 1.2 m/min

Title: Soldering device for flat modules such as PCB(s) - has two independently controllable nozzles providing two directed streams of liquid solder
Inventor: GRASMANN KARL HEINZ
IPC: B23K3/06
Filed: 1991-09-30
Abstract: A device for soldering flat circuitry, esp. p.c.b.'s with components mounted, transports the individual circuits along a track (14). A solder bath (2) under the track (14) is filled with liquid solder up to a solder level (4). First (24) and second (26) nozzles project up from the level (4) and have first (36) and second (50) mouths respectively, formed as long rectangular slits. The slits extend perpendicular to the transport direction. First (64) and second (54) pumps pump first (74) and second (7) solder streams through the respective nozzles (24,26). The nozzles (24,26) are independently controllable. The second (26) is operated after the first (24). The second nozzle (26) and mouth (50) are shaped so the second stream (70) flows against the transport direction. The first nozzle (24) and mouth (36) are shaped so the first stream (74) forms a wave from which solder flows partly in and partly against the transport direction. The mouths (36,50) are directly adjacent so the outflowing streams combine into a single wave. USE/ADVANTAGE - Esp. for SMD circuits. Enables accurate soldering. Prevents errors in shaded areas, bridges and oxidising.

Title: Yarn singulator for extracting single threads from fabric - has movement of hook shaped grippers, with min. width related to weave pattern, controlled by strain gauge
Inventor: GROSSMANN HANS
IPC: D03D3/04
Filed: 1991-10-05
Abstract: Yarn singulator has hook-shaped grippers (2). Min. width of the grippers relates to the weave pattern so that each thread appears at least once on the surface of the fabric. Two grippers (2) can be arranged on opposite sides of the fabric and can be constructed in lamellar form with an elastic region (4). Singulator is pushed against the edge of a fabric (1) and the grippers (2) move apart against the spring load provided by the bending of an elastic region (4). Deflection is measured by strain gauges (5) which provide a signal to control the forward movement of the device. As soon as the first thread has been caught, the grippers move together which gives the signal for the singulator to be retracted, bringing the thread with it. Pref. construction the grippers can be pivoted and can hinge against a spring. USE/ADVANTAGE - Picks up single threads from a woven fabric.

Inventor: KANG BONG-SOON
IPC: G06T11/20
Filed: 1991-12-23
Abstract: A coding method for storing characters in a ROM mounted in an on-screen display circuit for use in a VTR or TV comprises determining bar patterns (C1 ... C12) of a predetermined size in binary data from an image of the character. All of the distinct bar patterns obtained from a character set are then stored, and an address for each bar pattern is produced. Each character is then stored in ROM as a series of addresses of the stored bar patterns, each said address being associated with a respective column of the character. The method enables character data to be displayed on a TV screen to be coded and stored in a relatively small capacity. <IMAGE>

Title: Biological cleaning of coarse loose organic material - by using water in container with microorganisms to breakdown hydrocarbon(s)
Inventor: BARZ HANS-JOACHIM DIPL CHEM DR
IPC: C02F3/34
Filed: 1992-10-05
Abstract: For the biological cleaning of coarse inorganic material, soiled by hydrocarbons, the coarse-grain material and water are inserted into a watertight container in a vol. where the material is wholly covered by the water. Adapted microorganisms are added to clean out the hydrocarbons together with nutrients, vitamins and trace elements, and oxygen is delivered to the watery solution. The material is allowed to dwell in the container until the impurities have degraded or dissolved significantly. The coarse grain material is washed for further use. The sludge is removed and the water is extracted to give water containing microorganisms and some nutrient salts for return to the container, and the dried sludge is disposed of. USE/ADVANTAGE - The system is for soiled material such as railway ballast, which is subject to soiling by diesel fuel and lubricating oil deposited by trains. It can also be used to clean construction rubble and gravel. The method gives a simple and cost-effective cleaning action, where the cleaned material can be used again, such as railway ballast.

Title: Electronic control for fuel injection in IC engine
Inventor: WILD ERNST DIPL ING
IPC: F02D45/00
Filed: 1992-12-22
Abstract: The fuel injection requirements are computed from basic engine parameters, corresponding to a steady engine torque and from the changes in the engine dynamics. The correction signals are computed w.r.t. preset time intervals and are updated to take account of changes in the engine operation.The correction signals have different characteristics for acceleration and retardation. The correction process is applied after a set time interval, to eliminate transients. The correction signal is derived from the changes in engine torque with engine speed changes and from other changes in the engine dynamics.
